Working with Blended States: Mega-Qubit as a Tensor

As you start working with larger quantum circuits, you’ll analyze chunks of it at a time. Consequently, you’ll need to consider blended states that are the result of previous parts of your circuit. Consider the following circuit, where the bottom qubit is in a blended state:

Specifically, the bottom qubit has a single pentagon images/_pragprog/svg-17.png qubelet and a single triangle images/_pragprog/svg-18.png qubelet, as shown in the following figure. ...
